Currently, in the automotive industry, joining of the aluminum alloys with the steel is a crucial problem to be
solved. Conventional joining techniques including resistance spot and gas metal arc welding are not acceptable
for those applications due to a number of metallurgical problems. The investigation was carried out to develop
the hybrid joining process combining the resistance spot welding and brazing. In this study, an attempt was
made to apply hybrid process to the joining of dissimilar sheet metals, Al-Mg-Si (6000 series) alloy and low
carbon steel sheet. Hybrid process (resistance spot weld/brazing) using ¯ller metal was found to be e®ective
to overcome the incompatibility between aluminum alloy and steel. Although hybrid joining process of Al alloy
sheet and steel sheet did not produce acceptable bond strength, it was proved to have reasonable interfacial
bond layer if the optimal process condition was applied.
